AweMUD is a MUD server for use with fantasy-settings. Features include fully dynamic objects and characters, an advanced scripting system, and custom worlds. The engine will eventually have completely interactive rooms (items can be placed under benches, doors can be destroyed), complex magick, and interactive NPCs.

The BlinkenServ (or BlinkServ) is a project aimed at
developing software for the Simple Blinkenlights
Transport Protocol. It currently provides a graphical
server suite that features streaming, file sharing for
blm movies, and uploading of love letters and the
ability to play them on demand. It includes a stream
viewer (compatible with CCC's blccc) as well as a file
sharing client that uses the SBTP protocol.

C-Kermit is a combined serial and network communication software package offering a consistent, medium-independent, cross-platform approach to connection establishment, terminal sessions, file transfer, character-set translation, numeric and alphanumeric paging, and automation of communication tasks. Recent versions include FTP and HTTP clients as well as an SSH interface, all of which can be scripted and aware of character-sets. It supports built-in security methods, including Kerberos IV, Kerberos V, SSL/TLS, and SRP, FTP protocol features such as MLSD, and source-code parity with Kermit 95 2.1 for Windows and OS/2.

ConMan is a serial console management program designed to support a large number of console devices and simultaneous users. It supports local serial devices, remote terminal servers (via the telnet protocol), IPMI Serial-Over-LAN (via FreeIPMI), Unix domain sockets, and external processes (e.g., using Expect to control connections over telnet, ssh, or IPMI Serial-Over-LAN). Its features include logging (and optionally timestamping) console device output to file, connecting to consoles in monitor (R/O) or interactive (R/W) mode, allowing clients to share or steal console write privileges, and broadcasting client output to multiple consoles.

DataReel is a free, cross-platform database and communications toolkit. It can
be used to rapidly develop and deploy multi-threaded database and
communications applications. The DataReel toolkit is composed of a modular C++
library designed to build cross-platform infrastructures for end-user
applications, embedded systems, and reusable libraries. DataReel's unique
modular design simplifies adaptation, allowing you to determine the level of
complexity. DataReel makes Internet connectivity and database programming easy.

Exscript is a scripting language for automating
network connections over protocols such as Telnet
or SSH. It is in some ways comparable to Expect,
but has some unique features that make it a lot
easier to use and understand for non-developers.
It supports parallelization, logging,
authentication mechanisms, and a lot more.
